Potassium assists with muscle contraction, nerve functioning, and more. Potassium is an important electrolyte that can be found in plenty of tasty foods on the keto diet.
Consuming adequate amounts of potassium can help prevent symptoms of the keto flu, like muscle cramps (and other side effects associated with potassium deficiency). Rather than dive right into potassium supplements, you can first try to increase levels of potassium through diet! Here are five potassium-rich keto-friendly foods you should know about! 
Spinach is a highly nutritious leafy green vegetable. Just one cup (180 grams) of cooked spinach gives you 18% of the RDI for potassium . Not only is spinach a keto-approved food, it also provides nearly four times the RDI for vitamin A, ten times the RDI for vitamin K, and more! Leafy green veggies like spinach are also packed with antioxidants .
Try a spinach salad or sautéed spinach! Add spinach to a baked chicken dish or a stir fry! You could also try one of these delicious keto recipes starring spinach:
Avocados deliver a creamy, smooth, fatty texture and flavor and they’re a rich source of fiber, antioxidants, folate, and vitamin C, K, and B6. The nutrients in avocado are probably responsible for their positive effects on health [4,5,6].
Avocado has been shown to be beneficial for weight management, metabolic syndrome, and heart health.
The humble avocado is an excellent source of potassium and one medium-sized avocado provides 20% of the RDI .
Fatty fish isn’t just brimming with health-boosting omega-3 fats and protein, fish like salmon is also rich in potassium. Half a wild-caught salmon filet (around 187 grams) gives you 967mg of potassium, which is 18% of the RDI .
You’ll be happy to know the juicy, flavorful tomato is full of potassium. This includes tomato sauce and tomato products! One cup (244 grams) of tomato sauce provides 17% of the RDI for potassium .
Most renowned for its transformation into ketchup, the infamous tomato is actually a low-carb fruit that works well in salads, soups, pasta dishes, and beyond.
Just 100-grams (3,5 ounces) of clams gives you 18% of the RDI for potassium. Clams are also rich in other nutrients like selenium, iron, and vitamin B12! 
Clams are also high in protein and healthy omega-3 fats. These tasty little shellfish can also be advantageous for your health. Clams are linked to a reduction in inflammation and related diseases [16,17].
